A customer called last Tuesday morning. His garage was ice cold even though he'd been running the heater. After ten minutes of questioning, the answer became clear: his bottom seal had deteriorated years ago, and cold air was pouring in around the edges. He'd never noticed until December hit hard. That conversation happens more often than you'd think, and it's completely preventable.
Weather stripping and seals are your garage door's first line of defense against drafts, moisture, pests, and energy loss. When they fail, the cost isn't just discomfort. You're paying to heat or cool space that's leaking away. Worse, you're inviting rodents, insects, and water damage inside. If your Edwall home is showing signs of a draft near your garage, the culprit is almost always worn seals.
Garage door seals live a hard life. They flex thousands of times per year as the door opens and closes. UV light, temperature swings, and moisture all attack the rubber. In Edwall, where winters are cold and damp, seals typically last 5 to 7 years before they start cracking or peeling away from the frame.
You'll notice failure in several ways. Cold air flows into your garage even when the door is closed. You see daylight around the edges of the door. Insects or spiders appear more often. Moisture pools near the threshold after rain. Some people smell a draft before they see one. Any of these signs means your bottom seal, side seals, or threshold is compromised.
The bottom seal takes the most punishment because it bears the door's weight and contacts the ground every time it closes. It compresses, stretches, and eventually tears. The threshold, which sits under the bottom seal, can crack or shift out of alignment. Side seals shrink and pull away from the frame. All three need inspection at least once per year.
If you've noticed your garage struggling in winter, your seals might be part of the problem. We've covered winter garage door problems in Edwall in detail, but weather stripping is often the quickest fix with the biggest payoff.
A single-car garage with a failing bottom seal can lose as much heating energy as leaving a window cracked open all winter. That's not an exaggeration. Cold air enters, warm air escapes, and your heating system works overtime to compensate. Over a season, this adds up to real money.
If your garage is insulated (and it should be), failing seals undermine that investment entirely. Insulation only works when your space is sealed. Gaps around the door frame let conditioned air escape. The threshold and bottom seal are critical because they're where most air movement occurs.

Beyond energy cost, water intrusion is a silent killer. Even small gaps allow rain and snowmelt to seep into your garage. Over time, this damages concrete, drywall, and anything stored inside. Mold can develop in damp corners. In rural Edwall properties, this risk is especially high because garages often sit lower than surrounding terrain or experience poor drainage.
A proper seal replacement starts with inspection. We examine the bottom seal, side seals, threshold, and frame for damage. We check alignment because a door that's even slightly crooked won't seal properly no matter how new the seals are. We measure gaps and assess whether the frame itself needs adjustment.
The actual repair depends on what's wrong. A failing bottom seal is removed and replaced with a new one matched to your door type. Thresholds are cleaned, realigned, or replaced. Side seals and top seals receive the same attention. The cost varies based on door size and seal condition, but a basic bottom seal replacement typically runs between $150 and $400 in our area.

If you're also concerned about insulation or overall energy performance, read our guide to garage door insulation in Edwall. The two topics work hand in hand.
Not every seal issue requires a full replacement. Sometimes seals are simply dirty or slightly misaligned. A cleaning and minor adjustment solves the problem. Other times, seals have hardened or cracked beyond repair. Replacement is the only option.
If your door is older than 10 years and you're seeing multiple seal failures, consider whether a full door replacement makes sense. Older doors often have frames that have shifted, making new seals less effective. A new door comes with modern seals and a warranty. Compare the cost of replacing multiple seals against the cost of a new unit.
Don't wait until winter returns or pests move in. Weather stripping and seals are cheap insurance against bigger problems. Call us at (509) 331-7541 for a same-day estimate, or contact us online to schedule your inspection. We serve Edwall and surrounding communities in Spokane County.
Small gaps become big bills fast. Act now and keep your garage sealed tight.
How often should I replace weather stripping on my garage door? Seals typically last 5 to 7 years. Inspect them annually. If you see cracks, peeling, or gaps, replacement is due. Climate and door use affect lifespan.
Can I replace the bottom seal myself? DIY seal replacement is possible but tricky. The door must be secure during removal, and alignment matters. Most homeowners save time and frustration by hiring a professional same-day service.
What's the difference between a bottom seal and a threshold? The bottom seal is the rubber strip attached to the door itself. The threshold is the metal or rubber track on the ground where the door closes. Both must seal properly to prevent drafts and water entry.
Will new weather stripping reduce my heating bill? Yes, noticeably. Sealing drafts can reduce heating costs by 10 to 20 percent during winter months. The payback period is usually one to two seasons.
Do all garage doors use the same seal size? No. Seals are designed for specific door heights and frame types. Single-car, double-car, and commercial doors use different seals. We measure and match your exact specifications.
